RDA builds

Actually the coil with the higher resistance will produce very little heat in comparison to the lower resistance coil. Strangly in this bizzaro sinario the 22/22 coil would make most of the heat but take a long time to come up to temp because of the very high mass.

Hmm you might be right, I know if two coils are built with the same wire but one has more wraps the higher resistance will be hotter. But with the significant mass difference too, I am not sure how that would play out. Either way the results are not going to produce a good effect for the risk.

That would have to be a "whole lotta" wraps for twisted dual coil 22g to get .5 ohm................

No no no that's the one I was thinking about putting in it it's a 6 wrap

Depends on what you wrap it on. Using 2.5mm bit, it would only take about 8 wraps. With a 1.5mm "micro coil" it's still only about 11 (which is a bit too many for me)

ShadowAssasin, do you have an Android device? If so hit the Google play store and download the free app "Vaper's Toolbox" play around with that. It should help a lot.

I use a 3/32nd drill bit

Yeah i have a galaxy s6 edge plus ill go download it now Thanks man

A 6 wrap twisted 22g should ohm out around .2 ohm

PM me if you have any questions on it.

2.38 mm is 3/32 but good luck with that 22g twisted kanthal 8 wrap ever reaching .5 ohm, 11 wraps would be .3 ohm

Ok I must be tired, somehow i missed that it was twisted 22, I calculated based on single strand 22. You are of course correct that 11 wraps would be .3 with twisted. It would take 19 wraps to get to .5 ohm.

Is other way around. The coil with more wraps thus higher resistance will heat up slower. Two reasons, it has more mass and because it has higher resistance less current will flow through it.

That 6 wrap will over stress that 20a battery out !

It's a 35a battery

No, it's not.
It claims to be a 20 amp but I doubt those specs.

Also have a lavacell 30 a continuous

I haven't had a problem with it running .2 ohm builds the battery doesn't even begin to get hot

Yeah, good luck with that.

Just pointing out the obvious.
You are an adult and can make your own decisions, both good and bad.
I'm just giving you accurate information.

Same thing, except on this one, I wouldn't even give it a 30a max pulse rating ...............
